The moon travels the same path every day, east/west around the earth. It is 24,875 miles around the earth the train travels 1036 miles every day. The train speed in only 43.18 mph this is slow enough to swap out cars on side tracks for maintenance. 200 foot wide floating railroad tracks need to be built for the oceans. 1/2 mile wide sections of the bridge can open up every day for ships to pass. The bridge can be GPS located and powered by electricity in the tracts to keep the track in place. A train several miles long can generate mega watts of power to the rails. Think outside the box.
